survived the catastrophe remember. and they share private footage with us that's never been seen before. noble starts people 20 minutes on t w. a a. problem in society we have at the moment every one of the great of making a great what may happen if we don't do. the pandemic has changed life as we know it. but what comes next. pick up again. will we continue to innovate regardless of the cost.

live lives profit driven. and globally connected. or has this pandemic spark irreparable change. how we live in the future after the pandemic. hello and welcome to covert 900. 11 with this week we're taking a look ahead at life after the pandemic for what it means for cities to economies and even nutrition a recent study has linked higher obesity rates with higher coppa death rates the world obesity federation report says covert death rates were 10 times higher in countries where the population was on average overweight further almost 90 percent of cova deaths occurred in countries with high obesity rates the report calls for people living with obesity to have priority access to vaccines. i mean while the

pandemic itself has increased hunger and malnutrition around parts of the world take brazil for the 1st time a whopping half of brazilians don't have access to safe and nutritious food that's according to reddy pence on a local food research group lines are swelling by the day at soup kitchens and food distribution points in the country experts say the sharp increase in food insecurity is due to job losses caused by the pandemic. pulling back is assistant professor at the london school of hygiene and tropical medicine and she joins me from london police good to have you on the show what has the pandemic taught us about past choices when it comes to nutrition. and that mike has taught us that. that disruption and disruptive events and i lifestyle do lead to changes in the foods that we eat and the choices that we make so initial data shows that people certainly have changed my diet in

a pandemic for the better and less well for some people that improved and i had some for others and maintained diets west and what exactly that i did it wasn't that because i spend more time at home because i wasn't because other things in the supermarket were. or to have more time to cook their meals for example we don't exactly know yet but diets have certainly changed do you think that some of those obesity rates we mention just previously that that may lead some people to rethink perhaps the way they're eating or does it give people time during the what is it that makes people have a rethink. i think it time i certainly an issue there and what might be really interesting is to see you kind of isolate that group of people that started eating better started eating more fruits and vegetables and remember discounts in a. system where or in a world where

a very small proportion of people actually adhered to sufficient fashionables and the different guidelines in countries are by the w.h.o. quite a small percentage of here and you see that in a pandemic the proportion of people have very much increased. consumption of healthy food such as for eating vegetables and legumes and reduced unhealthy foods whereas others didn't so what would be really important and kind of a lesson that we can take out of. that defendant make going forward in terms of systems and diets but if you check this to see what what are those barriers that were removed by depend that meant 40 people that lead to these improvements of their diets in can we used to learn a little bit of about what sort of leverage points we have in a food system in supermarkets in homes of people in perhaps even further skills on

how to cook certain foods from from scratch that would remove those areas for others as well so that they could improve on their diets this one it sounds like you believe that some of these changed habits whether good or bad could stay beyond the pandemic. yes absolutely i think people certainly and again we're talking a little bit more about the group that experience than him improvement of their diets. might also be once that kind of got a little bit more in touch with. what they're actually doing on a. daily basis so it is less running out of the office going to the supermarket and buy a ready to eat meal and it's more cooking from scratch so you will be more aware naturally how much salt goes in there that's what cetera and and a few more of the unhealthy or if it's that we eat too much of it we also say so yes i guess. i just want to say we've also seen during spencer make that food supply itself has changed what is that meant for nutrition in terms of getting

fresh food. yeah it's a difference a really important lesson and something that perhaps. some scientists have been warning about for a while but actually it system is really quite fragile you see it in the u.k. i'm most familiar with the environment here but south certainly also in other countries and in europe and in fact actually everywhere globally and what we see is that most countries also have. they have stocks for only a few days here very much dependent on other countries one to 4 disclosed that that's really poses a problem to. the stock supermarkets for example but we also see those disruptions and in this case it was condemning that it could also be a natural disaster of climate change. rest in the southwest of the sourcing problem that we could certainly lead to all of a sudden products not being if they want to suit my pull prices going up and

especially trees and fresh polls we do get them often from. countries that are phoner a full 2 types of disruption and that could ultimately lead for example to increased prices of fruits and vegetables in new supermarkets which naturally them disproportionately affect those that struggle a little bit in buying their daily supermarket. and friendship i'm sorry to say that the break that also has obviously been changing some of the supply lines as well as what to ask how can we better plant food supply lines when we know what we've known from the pandemic and from bragg's that for example are there any lessons there. yes absolutely i think mapping out where everything is currently coming from how much of that is for example domestically produced what sort of like storage in stocks do we have and are there certain pivotal food groups that are particularly. vulnerable or non brazilian and

in that sense and ways how to inform to consumers but also to producers. about these vulnerabilities and see how perhaps there are some substitutions to make back to make food systems much more sustainable and make sure that the supply is resilient really quick because it could mean more growing locally for example instead of importing stuff yeah absolutely and especially because you know in a more sustainable world we would be looking at improving our. plant based food consumption. so that would we would need to find ways to source these things which. locally not to say that trait with. lower income countries or so is a bad thing per se of course daddy peace depend on export which are. global north as well but certainly looking at ways how to minimize the next inanities for your

health but also what he or i are meant to be something that we can improve upon or to leave it there pauline show big thank you very much london school of hygiene and tropical medicine. over to our science correspondent with a question that goes straight to the gut. you hear a lot about the micro biome in health what is it and why is it so important. the term micro biome describes the entirety of the microbial community that inhabits an organism like a human it's made up of a huge number of microorganisms even conservative estimates say that there are more microbes living in or on you then there are cells in your entire body carrying your own d.n.a. but because most microbes are much smaller than body cells if you put every one of

them in your micro biome on a scale it only way a couple of kilos with with most of the microbes coming from the gut the average human is home to over 10000 microbial species many of which play for example vital roles in digestion and over the last half a century scientists have discovered that the make up and the balance of those species and individuals micro biome plays a fundamental role and helpless and can be linked to many medical conditions just look for instance at a recent large scale study on aging and the micro biome the authors found that in the elderly reduced populations of common bacterial species in the gut were associated with overall better health aging people whose bacterial balance remained

more static over time didn't live as law on average although it's really tough to clarify cause and effect in a system as complex as as the human micro biome links to both health and illness have been established in fields from from allergies. science to cardiovascular disease to the neurological disorders like like all spiders it'll take a lot more research though depend on exactly in what ways it's important to specific health issues but many common diseases might one day soon be treated by tweaking a patient's micro biome. or science expert williams there that's our show today thanks for watching as always stay safe and we'll see you again soon.

and getting there isn't even that expensive at least not compared with the early days of manned space flight masters apollo missions of the 960 s. cost nearly 330000000 euros a shot space x. round trip cost a mere $43000000.00 the economic boom in space is a topic today here on made the business magazine on t.w. . long before space was recognized as a higher dimension for investors people saw the universe as a mysterious and often menacing realm it was the origin of asteroids that frequently blazed across the sky and sometimes even fall to earth causing huge destruction now we know that these celesio chunks of rock are incredibly rich in valuable resources that are difficult to mine here on our planet forward thinking entrepreneurs are looking beyond earth because a lot of it out there here's chris carla on mining metals in space.

on the 15th of february 2013 an asteroid entered earth's atmosphere over russia all . through. it created a fireball brighter than the sun hankie and. its shockwave injured more than 1000 people. for. good just like these show why asteroids balls a great threat to life on earth but they're also the reason why some see them as a golden opportunity this clip was watched many years of times on personal computers and smart phones. such small and powerful devices contain metals like gold silver and particle. piece resources are not just pretty damned the most conductive and durable and my level of elements.

are hiding important for magazine. aerospace. the bathroom and technology. but the painting them is an ugly process. mining destroys and buyers eco systems displaces communities. in great stocks waste . and there's a tragic irony but you know me used to make solar panels hydrogen and wind turbines . the more the water goes green the more toxic mining needs. our planet is not the only source of the special elements. to spearing earth deserve a speeding mining may lie in the planet's ultimate threat from the asteroids. this guy certainly is no longer the limit. and this is chris of the week

he was the co-founder in chief ostrog minor off but only 3 resources. the 1st company format would be explicit goal of mining asteroids he even have an asteroid named after him so i'm very grateful to have $136.00 are not in the wiki. some of the celestial bodies close to earth i'm credible treasure troves. golden flocking all are very heavy and over time they sank into a private school. that's why they're so rain on the arts crossed. but again because the actor is don't have much gravity that didn't happen i'm asteroids and in some cases there are 100 times as. much as a 15 for example i'm not sure of the best schools floorplan it was this thing needed to have more profit than it's ever been mined the earth. takes 16

cycle. which world said to be worth $700.00 quintillion soft on the us until now these were just your practical because space travel was just too expensive but that's changing. a seat on a space x. walk times cheaper than it was in the space shuttle started that you couldn't watch . chosen to have page the co-founder of google put his wealth behind planetary resources if you're after and you company joined the race to mine now stories and in 2017 nasa announced he would pay a visit to psyche. she's in the 18 stone she's the one leading such a mission. thank you wash in the rubble. but although the program is not about the asteroid mining it could lay the groundwork for a more sustainable future. crazy

as he sounds mining asteroids might not only be feasible but also much more sustainable that mining earth. one which interestingly. and just sign is a researcher who is actually crunched the numbers. actually turns out the answers seems to be yes he estimates that there are fewer necessary to go and bring back one kilogram of latino men would release 150 kilograms of c o 2 into the earth's atmosphere terrestrial mining generates 40000 kilograms of c o 2 so hostile at mining could be hundreds times less polluting essentially the main reason is there's almost no other substance you can mine which generates that much greenhouse gas and outsourcing mining to space could decrease pollution on

earth but there is an economic problem. long term that is a. gigantic win in terms of economic problem the problem if you mine like 5 times of the pattern then you have on earth right now means that the market prices were in the crash you can sell of the much more price which means you diminish your profit margin so your operating your infrastructure their loss and that makes a really unattractive for investors carbon taxes in new technologies could change this equation but it would still take several years for space mining to become profitable. investors decided to not wait for long the world doesn't quite support a business model that takes more than a $100000000.00 and more than 10 years to to make a return on that investment and maybe a trip. if you just company feel to tweeze enough funds forcing you to abandon its

goal of mining asteroids. we. just like in california trash space miners do not realize their dream of out of the small 12. planetary resources didn't succeed in their ultimate goal to mine asteroids but i think it succeeded in a lot of ways the steps to get there there wasn't much gold in california after all yesterday said they're succeeding something else. in the rush to get to different period they created the infrastructure that accelerated the development of the west. to the space miners are doing something similar. we are as a world a lot closer to using resources from space than we were when the company was founded in 2000 you know you know how to get a degree. but we could make it there. and i think in some ways.

new inventions can make space mining economical just a few decades ago the very technology you're using to watch the speed cindy impossible. now we can use satellites to be in the internet everywhere on the planet. 101520 years a lot can happen one day details money goes from a. bit like using candles to heat up your room. more such galactic business prospects will inevitably result in competition between companies and between countries who do the many treasures floating around in the universe belong to my colleague noir house has been looking into that question and he's discovered that the matter has been regulated so it's off.

bones outer space. you might think it's easy hop on a rocket landed on some celestial body plant a flag and it's yours or rather the country you work for. you think again when neil armstrong planted a u.s. flag on the moon in 1969 that didn't make it american appropriating land in space is actually banned under international law under the outer space treaty of 1967 more than 130 countries have signed the document it says all countries are free to explore space but not to appropriated for themselves outer space basically belongs to us all the treaty bans weapons of mass destruction from space and says its use shall be the province of all mankind that seems to rule out commercial ventures up there but the treaty is not comprehensive and has been overtaken by developments it

was born of the cold war between the us and the soviet union. nowadays china india and the european union are all drooling over the economic opportunity space might represent for now there are no traffic regulations there's no obligation to clear up space junk there's no international space authority with flight control functions for rockets and satellite launches each country goes its own way the odd entrepreneur just ignores the outer space treaty dennis hope of the united states says he found a loophole and ownership of the moon he sells plots of land up there 50000 square meters go for just $39.00 euros 90 you could get a nice certificate staking a claim is another matter on the internet you can also buy a house on mars for 890000000 euros but you can't move in until 2060.

real estate natural resources tourism business opportunities might soon abound. but what if some aliens turn up and say the entire cosmos is there. well if there is life out there you have got to wonder if we should bother getting in touch the space around our planet is already pretty crowded enough without physics is from another galaxy not only is there the junk left over by human space missions past but it's also becoming overrun with satellites over the last few decades that number has skyrocketed if you'll excuse the pun and 958 there were 2 satellites in orbit and the year 2000 they were almost 800 but last year we crossed the 2 and a half 1000 mark the number has been growing exponentially and it looks set to keep going. 3 to widen. the new era

is dawning as commercial enterprises drive advances in space technology with ambitious projects. even musk of tesla wants to outdo nasa with his space x. company. and fly people to know not the move but mars. space technology and space flight are essential to modern life as electricity from the grid we couldn't do without them. and their key to new and future technologies . spoke. in the european union 10 percent of economic activity already depends on satellite navigation. the e.u. launched its copernicus program in 2014 that satellites observe the earth from

orbit it's a publicly funded venture. the data the satellite sent home would enable the development of new applications for example software to enhance the fuel efficiency of ships. new jobs will be created. satellite data can be used to make marketable products. remote sensing solutions is a company based in munich that specializes in environmental monitoring it's not exactly a high margin industry copernicus has boosted revenues here as its data are freely available to all. the company uses them to create valuable information regarding the data are free or cheap the entire process of generating information is cheaper and people are more willing to buy in and we have it. so colorful. clients include nature conservation groups such as w w f and

a number of governments. one focus of the company's work is monitoring the impact of land use and climate change on vegetation. satellites can capture images of large swathes of land. vegetation in the sun hell can be tracked from season to season the. astronauts say they have a very different relationship to earth once they've been to the i assess the view from a satellite is a bit similar we can see how africa is doing or south america the view from far away enables us to see connections more clearly by that which on. the copernicus satellites are big and heavy they weigh tons it takes years to build them and each is unique. many components 1st have to be specially developed that makes the satellites expensive hundreds of millions

a year as each. unlike many satellites they can be as small as a wine bottle. the advent of small satellites marks a new era. there are a lot cheaper but still provide important services. planet labs is an earth imaging company in san francisco that already uses many satellites to photograph the globe. students throughout europe are learning to build the little devices one class of small satellite nano satellites a team of berlin's technical university devised the project to deploy 4 of them to enable faster transfer of large amounts of data. they were launched 2 years ago.

small satellites have the potential to revolutionize earth monitoring as well as global telecommunications. the start up smart small satellite systems does what it's name suggests it's a cube sats can exchange precise information about their orientation so as to point in the desired direction they cost tens of thousands of euro's a piece. in your tooth it's the miniaturization of electronic components that enable such development to lytton satellites may be getting smaller but that doesn't mean their overall performances are declining either one can deploy a lot of small ones for the price of a big $1.00 the company has launched 4 of its cubes set so far they're flying in formation to test 3 d. typologies for scientific measurements to do that they have to communicate with

each other negotiate and organize their positioning autonomously. this test is a significant step towards creating intelligent 3 d. satellite configurations. one application could be mapping the ash emitted in a volcanic eruption that would be of great value to commercial aviation. small satellites often put together using standard components. so it's easy to make a lot of them. and also to switch out components depending on the intended use. of space x. is planning to send 12000 small satellites into orbit as part of its starving project to provide internet to remote locations around the world. big projects like that spur the automation of satellite manufacturing it's comparable to what's happened in the auto industry in this regard us companies are far ahead of ones in europe. he said we in europe shouldn't just give up but aim to be players in these

markets of it's where the future lies the economic and commercial potential is going to be huge. because put into the i got at sort. analysts say the space industry is set for stellar growth. revenues in 2018 amounted to $360000000000.00. some forecasts say they could reach $2.00 trillion dollars in 2040. rocket factory oxburgh once a piece of the expanding space pie. it's developing a launcher for small satellites a pretty 2 rocket specifically designed for that purpose. until now small satellites have to hitch a ride if there's room when big launches such as the area and set off into space. it's not very expensive but the waiting list can be long.

but in cost launches a big launcher is like a bus you have to wait to everyone's. onboard a small launcher is like a taxi it to where you want to go more cheaply and efficiently that's great for creating a small satellite constellation. about 100 companies are developing many launches many will probably fall by the wayside 3 are based in germany rocket factory aims to offer affordable and flexible satellite launches 10000000 euros a shot compared to 130000000 for an arianne. to keep costs down its launchers will contain many standard components from the auto industry. but it's designing the propulsion systems from scratch and will 3 d. printer a lot of the parts. big

launches such as arianna a very complex and post lots of expensive custom components they take ages to build by contrast r.f.a. aims to develop and deploy its 1st launcher within just 3 years. will be financially viable with one launch a month but we want to see a launch a week the whole thing should be so industrialised and automated that it's no longer anything special flying on tween braman in munich is not a big deal but it was a century ago we want to see the same thing with rockets. small satellite launch vehicles are set to make getting into orbit more affordable potentially opening up the heavens to a whole range of new ventures. the vastness of space presents another problem for any potential business activity there the logistics of covering huge distances in a practical amount of time if any there was some sort of system like teleportation

that works in star trek but could it work in reality my colleague has been investigating. a long time ago when space ships were made of paper plastic. and it snowed powdered al and many m. during the dean materialization process people then things were magically beamed about in star trek films. how nice would it be if we could be in ourselves around the globe teleportation instead of airplanes and c o 2 emissions think about how beneficial it would be for the climate alone in today's physics in fact teleportation is no longer science fiction. i'm always surprised about all the weird things that happen. my well your heart is

a quantum physicist at the australian economy of sciences is excursions into space travel and just a hobby work he explores the weird and wonderful world of teleportation of quantum teleportation to be precise as a having watched our trek for instance people imagine that you somehow beam matter or even energy because that's how it's done on the show that people disappear in the transporter and then reappear on an alien planet when. the similarity is that the system rebuilds the object identically in another place. or what's more at the exact same time or instantaneously regardless of the distance involved that's how the quantum world works via quantum entanglement einstein thought it was pretty spooky transferring information faster than the speed of light so does this mean travelling not only with 0 emissions but also with 0 delay.

what happens with quantum teleportation is that really just that you want him information in this system is transferred to another place onto another identical system. about what the matter itself atoms are photons or whatever it's made of does not get transferred so it doesn't disappear. but what does disappears the information it gets destroyed. still. so if 2 quanta are connected this way they can exchange information without a moment's delay but not the matter it really is just the information. ok then couldn't i just split myself into quanta and send their information to another entangled quantum cloud i mean then it would just need to be reassembled correctly right. let's just say that right now we don't know of anything that would

fundamentally speak against it but it would have to work in a completely different way but. we'll need completely different set ups than what we're creating now. if i could build a device that could do this and you'd ask me whether i would put myself inside it i'd say no. so mr spock would probably have to get beamed in a glittery shower of aluminum grey like in the old days. and don't forget the enterprise at least sped through the universe powered by an anti matter and hydrogen engine with not even a whiff of emissions. by the way a piece of trivia for you the words you me up scotty whenever said precisely in better form of the subject serious maybe other work with the me apart.

and that's all from this edition of made see you next time until then good bye and keep watching the skies.
